can be instantiated as an unlimited number of functions, it seems that we do not need a smartptr constructor, we need a constructor template. Such a template is an example of a member function template (member function templates) (also known as member templates)-a template that generates member functions for a class: 1 template2 Span style= "color: #0000ff;" >class Smartptr { 3 public : 4 Templa
Template definition: A template is a tool for implementing the code reuse mechanism, which can implement type parameterization, that is, to define the type as a parameter, thus enabling real code reusability. Template can be divided into two categories, one is a function template, the other is a class template. function templates are for functions that differ only in parameter types, and class templates are

First, Introduction:
A security template is a new feature of Windows 2000. It is a physical representation of the security configuration, consisting of a file (. inf) of the security properties supported by Windows 2000. It organizes all existing security attributes into one location to simplify security management. Security templates contain seven categories of security information: Account policy, local policy, time log, restricted group, file syste

Template Schema Definition: Defines the skeleton of an algorithm in an operation, delaying execution of some steps into its subclasses.In fact, Java abstract class is originally template mode, so the use is very common. And it's easy to understand and use, so let's start with an example: Public Abstract classbenchmark{/*** The following action is what we want to do in the subclass*/ Public Abstract voidBenchmark (); /*** Repeated execution of benchmark times*/ Public Final LongRepeat (in

The tuple in c++11 is an n-ary variable tuple, which is equivalent to a struct with n elements, except that the members of the struct are anonymous, and a Get () method is provided in the tuple to get the value of the element corresponding to the subscript. You can also construct a tuple object by using the Make_tuple () method. The specific usage is as followsWe know that the number of elements in a tuple is indeterminate, and the type of each element is specified by a template parameter, so ho
